GENERAL  INFORMATION 


What  Artisan  Courses  are  Offered. — The  artisan  courses 
herein  described  are  a  part  of  the  work  given  during  the  summer 
at  the  University.  They  are  arranged  in  two  groups.  The  first 
group  consists  of  courses  in  Electrical  Engineering,  Engineering 
Drawing,  Industrial  Arts,  and  Mechanical  Engineering;  the  second 
group,  of  nine  courses  in  the  various  lines  of  shopwork. 

Other  Courses — Other  courses  are  offered  of  the  character 
usually  taught  in  a  first-class  high  school,  as  follows :  algebra, 
geometry,  chemistry,  physics,  free-hand  drawing,  and  the  English 
language.  These  will  be  valuable  to  all  who  have  not  had  such 
studies.  They  may  be  taken  together  with  artisan  courses.  For 
information  concerning  these,  address  the  University  Editor  for 
Summer  Term  Bulletin. 

When  They  are  Given — The  artisan  courses  are  given  six 
days  a  week,  as  follows :  First  Group,  from  June  21  to  July  17, 1909 ; 
Second  Group,  from  July  19  to  August  13,  1909. 

Who  Should  Take  Them — The  courses  will  be  helpful  to  the 
following  persons : 

(a)  Those  who  already  have  a  trade  or  part  of  one  and  who 
desire  to  get  some  theoretical  training  and  practical  work  in  the 
drawing  rooms,  laboratories,  and  shops;  as  stationary,  locomotive, 
and  erecting  engineers,  oilers,  firemen,  custodians  of  large  buildings, 
boiler  makers,  engine  builders,  foremen,  superintendents,  machinists, 
draftsmen,  designers,  skilled  artisans  and  mechanics,  electricians, 
switch-board  attendants,  wiremen,  electrical  linemen  and  repairmen, 
salesmen  in  mechanical  and  electrical  lines. 

(b)  Those  who  desire  to  hold  positions  similar  to  those  above 
mentioned,  but  who  now  find  it  impossible  to  obtain  an  opportunity 
to  serve  an  apprenticeship. 

(c)  Those  who  have  obtained  a  fair  knowledge  of  the  theory  of 
a  subject  from  correspondence  courses  or  reading  and  who  now 
need  personal  instruction  and  practice  in  it,  such  as  may  be 
obtained  in  the  laboratories  and  shops. 

Employers  Benefited — Proprietors  of  engineering  and  manu¬ 
facturing  establishments  can  benefit  themselves  by  sending  certain 
of  their  employees  to  the  University  to  take  two  or  more  of  these 
courses,  with  the  expectation  that  when  they  return  after  four  or 
eight  weeks  of  study  and  laboratory  or  shop  practice  they  will  be 
more  capable  and  valuable  men.  Such  has  been  the  experience  of 
employers  who  have  tried  it.

Certificates  of  Work  Done — No  university  credit  or  diploma 
will  be  given  for  artisan  courses;  but  when  requested,  a  certificate 
will  be  given  to  the  student  by  the  Dean,  stating  the  courses  that  he 
has  pursued  satisfactorily. 

How  to  Gain  Admission. — No  examinations  will  be  required  of 
those  applying  for  admission  to  these  courses.  One  should  be  able 
to  read  and  write  and  should  have  a  working  knowledge  of  arith¬ 
metic  for  any  course.  For  some  courses  one  or  more  years  of 
practical  experience  is  quite  desirable.  Persons  should  be  preferably 
over  eighteen  years  of  age. 

In  making  application  for  admission,  information  on  the  follow¬ 
ing  items  should  be  given  in  considerable  detail : 

1.  Age. 

2.  Amount  of  grammar  school,  of  high  school,  of  correspond¬ 
ence  school,  of  collegiate  training  received. 

3.  Amount  and  kind  of  experience  in  practical  work. 

4.  Courses  of  study  by  subject,  and  by  letter  or  number,  that  the 
applicant  desires  to  take. 

Selection  of  Work. — One  should  be  careful  to  select  only  such 
courses  as  he  is  confident  he  can  carry — an  elementary  rather  than 
a  too  advanced  course.  It  will  be  found  wise  to  select  one  three-hour 
course  in  laboratory,  shop,  or  drawing  for  each  one  hour  of  daily 
recitation.  A  total  of  three  courses,  or  in  special  cases  four,  should 
not  be  exceeded.  The  hours  assigned  to  the  courses  should  be 
noticed  so  as  to  avoid  conflict  in  time. 

When  a  selection  has  been  made,  it  should  be  submitted  in 
writing  to  the  Dean  as  early  as  possible,  so  that  the  number  in  each 
course  may  be  known.  Early  applicants  will  be  given  the  preference. 

How  to  Register — All  students  are  urged  to  register  on  the 
days  set  apart  for  that  purpose,  at  the  Registrar’s  Office,  University 
Hall,  west  end  of  the  first  floor.  For  the  first  four  weeks,  register 
on  Monday,  June  21,  and  for  the  second  four  weeks,  on  Monday, 
July  19,  1909.  It  is  extremely  important  to  the  student  that  he 
should  be  present  on  the  opening  day. 

Tuition  and  Fees — Tuition  is  free.  A  registration  fee  of  six 
dollars  is  charged  each  person,  whether  one  or  more  courses  be 
taken.  One  registration  fee  is  sufficient  for  both  four  weeks.  This 
fee  must  be  paid  before  attendance  at  classes  begins,  and  cannot  be 
refunded  except  in  case  of  extended  sickness  or  unforeseen  calamity 
before  the  middle  of  the  term.  No  other  charges  will  be  made  ex¬ 
cept  for  materials  used  in  the  shops  and  chemical  laboratory,  and 
for  a  gymnasium  locker,  if  desired. 

Rooms  and  Board. — Board  and  lodging  can  be  obtained  near 
the  University.  Rooms  accommodating  two  persons  may  be  had

Artisan  Courses 


at  prices  ranging  from  $8  to  $12  a  month.  Rooms  with  board  will 
cost  from  $4  to  $6  a  week.  It  is  quite  possible  to  cover  all  expenses, 
including  books,  but  not  including  transportation,  in  the  artisan 
courses  of  one  group  for  $30,  and  of  both  groups,  eight  weeks, 
for  $50. 

To  Whom  to  Write. — For  further  information  concerning  rooms, 
board,  registration,  or  admission  address  the  Secretary,  Professor 
George  D.  Hubbard,  Ohio  State  University,  Columbus,  Ohio.
